The object of the present invention is to provide a mandrel mill capable of producing a seamless pipe without flaws such as necking. The mandrel mill of the present invention includes a plurality of consecutively provided grooved-roll stands and a mandrel bar 3 provided in a roll groove array formed by the grooved-roll stands so as to continuously elongate a hollow shell 2. Roll grooves 4 of at least a first stand and a second stand are arranged so as to satisfy conditions represented by the following formulas (1) to (4): b≦10a+1.5 (1) b≧10a−0.2 (2) b≦−a+1.5 (3) b≧−a+1.15 (4) wherein a=S/R1, b=C/(R1−S).

A flaw detection apparatus and flaw detection method for automatically detecting the occurrence of a flaw in a mother tube manufactured by rolling a hollow shell using a mandrel mill are provided. A flaw detection apparatus (100) according to the present invention includes a wall thickness gauge (1) which is installed on the exit side of a mandrel mill (M) and which measures the tube wall thickness in each of the reducing directions of a hollow shell (P) in the #1-#5 stands of the mandrel mill, rolling load measuring devices (2) which measure the rolling load in the #1-#5 stands, and a decision unit (3) which determines whether there are flaws in the mother tube based on the measured value of the tube wall thickness in each of the reducing directions of the hollow shell (P) and the measured value of the rolling load in each stand. The decision unit (3) determines that a flaw has occurred in the mother tube when the measured value of the tube wall thickness in any of the reducing direction in the #1-#5 stands locally varies by at least a predetermined amount and the measured value of the rolling load in any of the #1-#5 stands locally varies by at least a predetermined amount.

To conduct conversation without confusion in a virtual space while sharing a plurality of topics, send origin channel #CHOCOA, destination channel #meeting and message sending conditions are correlated and given to a chat server or chat client. If, for example, “USER1, USER3, USER4” are designated as sending conditions, only messages from designated users are sent from message origin channel #CHOCOA to destination channel #meeting. Meanwhile, messages from “USER1, USER3, USER4” can be displayed on message origin channel #CHOCOA or not displayed.
摘要:
A surface-treated steel sheet has a zinc-based or an aluminum-based plated steel sheet, a surface-treatment coating being formed on the surface of the zinc-based or aluminum-based steel sheet by applying and drying a surface treatment coating composition thereon, and a top coating being formed by applying and drying a coating composition for top coating on the surface-treatment coating. The surface treatment coating composition contains a water-epoxy resin dispersion, a water dispersed polyurethane resin, a silane coupling agent, and phosphoric acid and/or a hexafluorometal acid. The coating composition for a top coating contains a high molecular weight epoxy group-containing resin average molecular weight of 6,000 to 20,000.
摘要:
A notification is sent to a group of information terminals that conduct simultaneous communication by participating in a channel. The status change notification system includes a database DB and monitoring means 1. The DB is disposed outside the channel. The monitoring means 1 monitors an occurrence of a status change in the DB, and generates a notification of a status change when a status change occurs. At least one of the group of information terminals includes notifying means 3. The notifying means 3 receives a notification of status change from the monitoring means 1. The notifying means sends the notification to other of the group of information terminals to notify of the status change in a broadcasting manner.
摘要:
A communication management system is adapted for a chat system provided in a computer network including a plurality of client workstations and a server computer linked thereto. The communication management system includes a log file recognizing part which recognizes recognizing a log file produced at a predetermined channel of the chat system during a chat session between the plurality of client workstations and the server computer even when the client workstation of concern is not connected to the channel of the chat system. A storage part stores the log file recognized by the log file recognizing part. A log file output part transmits the log file, stored by the storage part, through the computer network to an external communication device provided outside the chat system, when a log file request transmitted by the external communication device is received by the log file output part.
摘要:
When actuation of an application program is received by a client, the client is connected with a chat server and participates in and registers at a channel, and attribute information, a number of times of statements or amount of statements in the registered channel is displayed, without a user's predetermined operation and a publicly known conversation process is executed. Thereafter, when designation of the displayed attribute information, number of times of statements or amount of statements is received, a channel where statements are possible is changed into a channel relating to the designation.
